Short display images by date newer to older in PHP -
i'm using following function read directory , show images gallery, works well, need display images ordering date newer older.
knows how using method?
function getpictures() { global $page, $per_page, $has_previous, $has_next; if ( $handle = opendir("saved/2013") ) { $lightbox = rand(); $count = 0; $skip = $page * $per_page; if ( $skip != 0 ) $has_previous = true; while ( $count < $skip && ($file = readdir($handle)) !== false ) { if ( !is_dir($file) && ($type = getpicturetype($file)) != '' ) $count++; } $count = 0; while ( $count < $per_page && ($file = readdir($handle)) !== false ) { if ( !is_dir($file) && ($type = getpicturetype($file)) != '' ) { if ( ! is_dir('saved/2013') ) { mkdir('saved/2013'); } $strfilename = "saved/2013/".$file; echo '<div id="imagen-t">'; echo '<p>' .date( "d d m y g:i a", filemtime($strfilename)) . "</p>"; echo '<p><a href="saved/2013/'.$file.'" rel="lightbox['.$lightbox.']"><img src=saved/2013/'.$file.' alt="" width="220" /></a></p>'; echo '</div>'; $count++; } } while ( ($file = readdir($handle)) !== false ) { if ( !is_dir($file) && ($type = getpicturetype($file)) != '' ) { $has_next = true; break; } } } } here result: http://www.espigoplatja.com/whale/galeria/

have looked @ usort: http://php.net/manual/en/function.usort.php allows sort array values user defined comparison function.
an example
<?php function my_sort($a,$b) { if ($a==$b) return 0; return ($a<$b)?-1:1; } $a=array(4,2,8,6); usort($a,"my_sort"); $arrlength=count($a); for($x=0;$x<$arrlength;$x++) { echo $a[$x]; echo "<br>"; } ?>
